Miharu
Chiharu's cousin. She, like Yuriko, does not possess the large breasts of her aunt or other two cousins, but is still larger than Yuriko.
She works many part time jobs to fund private detectives who search for her father who vanished a number of years ago.
She is a rival for Densuke's affections, but does not go to the extreme of Mikito or Yuriko, nor is she as shy as Chiharu. She once went on a date with Densuke.
Miharu only does not appear in the OAV but does in the Japanese radio drama. She is voiced by Jun Shikano.
